IMPROVEMENT IN APPARATUS FOR THE MANUFACTURE OF LAMP-BLACK.

Specification forming part of Letters Patent No. 222,337, dated December2, 1879;

l March 5, 1879.

To all whom itmay concern:

Be it knownthat I, HENRY B. WINSLow, of Marblehead, in the county ofEssex and State of Massachusetts, have invented a new and ImprovedApparatus for the Burning of Oil in the Manufacture of Lamp -Black, ofwhich the following is aspecification.

My invention relates to a furnace for burning oil' for the production oflamp-black; and consists in a certainnovel construction, Whereby the useof water is dispensed with and the character of the production improved.

My furnace is shown in the accompanying drawings, wherein- Figure l is avertical longitudinal section. Fig. 2 is a front elevation, partially insection.

Similar letters of reference indicate corre- I prefer to build thefurnace Adouble, as shown. It is to be built of brick lined withfire-brick, with-a rear wall, a, that divides the furnace-room from thecondensing-room, side walls, b b, front 0, and central dividingwall, d,

- that divides the furnace into two long and r narrow fire-spaces, e e.

The bottom of the fire-spaces e is formed by a sheet-iron plate, f, thatis supported by the walls, and the space 6 below plate f serves as anair-space through which ,air may circulate by openings 9 in the frontand sidewalls, this circulation of air tending to keep the plate f cool.

The rear of the fire-space 6 extends upward and communicates by anopeningflt, through the wall with the condensing-room. In the frontwall, 0, there is an opening to each 'firespace 0, and a door, 1', toeach opening.

The oil or other liquid is to be suppliedby pipes 70, that enter fromthe outside near the rear of the fire-spaces. The outer end of each bythe doors.

application filed pipe is is fitted with a cup-shaped receptacle, Z,into which the oil will run from the vertical branch of the mainsupply-pipe m, so that the amount of oil running into eachpipe k may beobserved and regulated by a cook. The pipe m will supply the oil to oneor more furnaces and the supply of material to each furnace will beseparately regulated.

No burners are employed, but I prefer to place in the fire-spacesbeneath pipes 70 shallow cast-iron drip-pans o to receive the oil, andthe oil running in faster than it will burn will drop while on fire tothe pans 0; and be spattered into small particles. These pans are to bechanged frequently, access to. them being obtained by doors 2'.

p is a slide andi a door, both of which close air-tight, while byopening the slide more or less the ingress of air may be regulated.

By constructing the fire space 0 long and narrow the plate f is morereadily kept cool, and the space in'front of the pointofcombustionrenders the smoke less liable to escape The products of combustion passthrough the opening it to the condensing-room, which will be lathed andplastered, and if the room is sufficiently large a number of furnaces,A, may be fitted to discharge into the same room.

Having thus described my invention, I claim as new and desire to secureby Letters, Patent-- I l I A lamp-black furnace having walls-a. b c d,with openings g, spaces e e separated bymetallic plate f, and oil-supply pipes, all arranged as shown and described.
